What number must be added to the expression below to complete the square?
2 answers:
Answer:
1/4
Step-by-step explanation:
To complete the square, use the formula (b/2)^2
The Quadratic Formula is: a+bx+c
thus a = x^2, b = -1
You then plug in the numbers in the formula above
(b/2)^2 = (-1/2)^2 = (1/2)^2 =1/4
D. 1/4
Explanation:
a perfect square is written in the form
(1)
In our problem, we have this perfect square:
(2)
with C being unknown. However, by comparing (1) and (2), we know that

So, we find

and therefore, the missing term must be

so the complete square is

Answer:
70 degrees
Step-by-step explanation:
L = w+22
2(l+w) = 4040
2(w+22+w) = 4040
2w + 22 = 4040/2 = 2020
2w = 2020-22 = 1998
w = 999ft
l = w+22 = 999+22 = 1021ft
w = 999 ft
B is 50 and A is all of them?
Answer:
see below
Step-by-step explanation:
1.)
(0, 4)
(1, 7)

y = 3x + b
(4) = 3(0) + b
b = 4
y = 3x + 4
Rate of change: 3 initial value: 4
2.)
(0, -5)
(1, -3)

y = 2x + b
(-5) = 2(0) + b
b = -5
Rate of change: 2 initial value: -5
